The absence of datablock properties "will certainly be resolved soon as the need for them is becoming obvious" said the [[http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.67/Python_Nodes|Python Nodes release notes]]. So this patch allows Python scripts to create ID Properties which reference datablocks.
This functionality is implemented for `PointerProperty` and now such properties can be created with Python.
In addition to the standard update callback, `PointerProperty` can have a `poll` callback (standard RNA) which is useful for search menus. For details see the test included in this patch.

Setting all values of a tuple is such a common operation that it deserves its own macro.
Also added Py_INCREF_RET to avoid confusing use of comma operator.
Nothing related to rigify actually, recent hack in py handling of IDProp (rB3346ab03)
was breaking integrity of IDGroup's listbase of children IDProps...
Took me hours to nail this down, should have bisected for once. :/
The issue is that we've got hell with DEBUG and _DEBUG,
theu're defined really inconsistent acros CMake and SCons.
Used more reliable NDEBUG definition for IDP_spit.
- calc normals only check flag when needed.
- keymap, dont get name unless its needed.
- keymap, avoid property lookup.
- idprop debug print, include pointer, helpful for troubleshooting.
- PyLong_FromSsize_t --> PyLong_FromLong
- PyLong_AsSsize_t --> PyLong_AsLong
In all places except for those where python api expects PySsize_t (index lookups mainly).
- use PyBool_FromLong in a few areas of the BGE.
- fix incorrect assumption in the BGE that PySequence_Check() means PySequence_Fast_ functions can be used.
comparing keymaps was too sloppy or too strict, now sloppy keymap comparison works by setting all the operator
properties to their default values if they are not already set, then compare this with the keymap item (ignoring values missing from either one).
... this way any non default keymap setting wont match with an operator menu item which doesnt set this operator at all (a problem sighted in this bug report).
developer notes:
- IDP_EqualsProperties_ex() function adds an argument to treat missing members of either group to act as if there is a match.
- WM_operator_properties_default() function to reset RNA values to their defaults.
- add IDP_spit(), debug only function to print out ID properties.
